BABY Audio has released Magic Dice, a free VST, AU and AAX plugin. They say:
Magic Dice generates random and lush wet-FX textures on demand. It puts the algorithmic firepower – and modern sound – of BABY Audio's Spaced Out plugin into a fun and unpredictable experience. Get anything from hazy space echoes over lush reverbs to alien-sounding modulation effects. The combinations are endless – and you'll never hear the same result twice.
